Patent ES-416239-A1 (ES)
Title: Steam generator
IPC: F22B1/02
Filed: 1973-06-25
Abstract: A pressurized-water coolant nuclear reactor steam generator has a vertical housing for the steam generating water and containing an upstanding heat exchanger through which the pressurized-water coolant passes and which is radially surrounded by a guide jacket supporting a water separator on its top. By thermo-siphon action the steam generating water flows upward through and around the heat exchanger within the guide chamber to the latter's top from which it flows radially outwardly and downwardly through a down-draft space formed between the outside of the jacket and the housing, to the bottom of the guide jacket for return upwardly therethrough. The water separator discharges separated water towards the outside of the guide jacket to mix with the water which flows downwardly. The housing has a feed water inlet opening adjacent to the lower portion of the heat exchanger around which, via a preheater, the feed water flows, providing preheating of the introduced feed water. However, all of the feed water required is not sent through the preheater for preheating, a portion being introduced directly and mixed with the separated water discharged by the water separator, this portion being proportioned as required to condense any steam carried along with the separated water discharged by the water separator.

Title: Method and apparatus for doffing full packaged bobbins in a fly frame
IPC: B65H67/04
Filed: 1975-10-03
Abstract: This invention is applicable for carrying out the doffing operation of several types of fly frames such as a fly frame provided with an upper rail having a plurality of flyers in suspended condition and a mechanism for driving these flyers therein, and a fly frame provided with a spindle rail and a bobbin rail disposed at a position above the spindle rail in such a condition that the bobbin rail can be displaced vertically during the building motion. According to the doffing method of the present invention, when it is required to carry out the doffing operation, the bobbins containing a full yarn package are relatively displaced to a position free from the corresponding flyers and the engagement of the bobbins with the corresponding bobbin driving mechanisms is released. Next the bobbins containing a full yarn package are carried toward a longitudinal end of the fly frame in a space above the arrangement of the bobbin driving mechanisms. In the preferable embodiment of the present invention, the carrying passage of the bobbin coincides with an alignment of the axial centers of the flyers arranged in the longitudinal direction of the fly frame. A chain conveyer is preferably used for carrying the bobbins. When the bobbin are carried to a longitudinal end of the fly frame, they are discharged from the fly frame. A fresh bobbin supplying device for supplying bobbins to the chain conveyer can be satisfactorily used.
